Model of benzene, ethane, ethene, ethin

MACHINE TRANSLATION (not authorised yet)

Set of 4 models: benzene, ethane, ethene, ethylene. This series contains enough parts to make 4 organic molecular orbitals models. The models show: sigma bonding orbitals, pi bonding orbitals, the concept of hybridization and delocalization.

Kit includes:

    H hydrogen atoms, 18 pcs,
    carbon C atoms, 12 pcs.
    sigma bonds, 27 pcs. (9 carbon-carbon bonds, 18 carbon-hydrogen bonds)
    pi bonds, 9 units.


Worth knowing...

Pi (π) bond: is a chemical bond formed by the lateral superposition of atomic orbitals (ignoring s orbitals), and the molecular π orbital determines its shape.

Sigma bond (σ): it is a chemical bond formed by the frontal overlap of two atomic orbitals, thus creating two new orbitals: a bonding and an anti-bonding. The σ molecular orbital determines the shape of the σ bond.

Delocalized electron - a single electron involved in the formation of more than 1 bond. This situation usually occurs when the p orbitals (orbital) of multiple neighboring atoms in a molecule are close enough together to overlap equally.
